Early Test Design -- Deacon
Carl,
Here's what I could glean from the internet sources on the basic Deacon sounding rocket. The main diameter is roughly 6.6" diameter, and the booster (including tube and nozzle) is 109.2" long. From the photos of that nozzle, it appears to be about 9" long, so if we subtract that from the total, we get 100", which means it would be the ST-6100 designation on the tube.
Looking at the fins, they're shaped much like the IRIS, just smaller. I'm guessing the dimensions as 2BT in width, 3.5BT root length, and 2.5BT tip chord, parallel to the root.
The total length of the rocket was listed as 129.12", or a nose cone of about 20" in length, giving us a 2" length for the model. I don't know if the original used a conical or an ogive profile.
Designations might be BC-620C for a conical, and BC-620 for the ogive. I'm suggesting a 0.5" shoulder length.
For the model, we would get:
Length: 12.00"
Diameter: 0.650" (ST-6)
Fin Span: 3.25"
Weight: 0.37 oz
1/2 A3-4T......359'......Dv 2 FPS......36" x 1/8" rod
A3-4T.........701'......Dv 27 FPS......36" x 1/8" rod
A 15" x 1.5" streamer is suggested for recovery.
Submitted for your approval...
